IMPROVEMENT IN CAR-COUPLINGS..

Specification forming part of Letters Patent No. 182,055, datedSeptember 12, 1876; application iled August 24, 1875.

To all whom it may concern:

Be it known that I, ARTHUR L. BLUNT, of Johnstown, in the county of Rockand State of Wisconsin, have invented a new and useful Improvement inRailway-Car Couplings, which improvement is fully set forth in thefollowin g specification, reference being had tothe accom panyin gdrawings.

The object of my invention is to accomplish the coupling of cars' bytheir own motion in coming together, doing away with the services of aman, and the danger incident to the same between the cars, the operationof uncoupling being accomplished by a man on top or upon the platform ofcar.

The invention is illustrated more fully by the side elevation, Figure 1,andthe end view, Fig. 2, of the drawings. Fig` 3 represents a plane viewofone-half of the clutch, which is an exact counterpart ofthe otherhalf.

A, Fig. 1',- represents the machine when closed, composed of doubletongues b b, being Wedge-shaped,provided with a slot in each to receivethe dogs c c under which they slide, and when closed forming a perfectdouble L clutch. B B are standards, each supplying the place ofthe endof a car to which is attached the levers d d, by hinged connectingrods,with dogs c c, for the purpose of raising the same by a man on topunlocking the coupler. E E are springs extending out from standards B B,for the purpose of throwing the dogs back into place. One standard, withits attachments, belongs to each end of the car.

D D, in Fig. 2, represent levers with fulcra at standard B, extendingunder arms f f,`

working in the guide-posts E E', by which dogs c c are raised, and thecoupler unlocked by a man at the side of the car. Arms ff are soarranged that when either of the levers d d or D D is operated both dogsare raised, and the clutch unlocked by one motion. Slides g g areprovided to hold levers d d down, and keep the clutch unlocked, ifdesired.

The object of making the clutchor coupler double is so that by attachingone-half of the coupler to each end of each car they will match eachother, and lock themselves when they come together, Whichever end'lnaymeet, and the cars in that case will always couple together unless it isdesirable they should not, when the clutch can be fastened open by meansof slides g gl i This coupler is to take the place of the bumper, and bepermanently attached to the end ofthe car, so that in running two carstogether they will be rmly locked without any human aid. Y

I do not claim the principle of a self-coupler, as I -know such couplershave been known and used but y Iclailn as my invention, for which Idesire to obtain Letters Patent- Y The combination of the double clutchin a coupler, with the wedge-shaped tongues b b, and the dogs c c,springs E E, levers d l and D D, connecting-rods and arms ff,substantially as described, and for the purposes set forth. y
